Solar-Storage Investments Hit $25 Billion in First Half of 2026

BloombergNEF reports co-located solar-plus-storage projects attracted $25 billion in investments during the first half of 2026, nearly double the second half of 2025 and three times the first half of

BloombergNEF recorded $25 billion in investments for co-located solar-plus-storage projects during the first half of 2026. This figure represents nearly double the investment recorded in the second half of 2025 and three times the amount invested in the first half of 2025. The United States and Australia were the leading markets for this segment, while global renewable energy investment reached $327.5 billion for the same period.

The scale of this investment reflects accelerating deployment of solar-plus-storage systems designed to integrate generation and storage at the same site. This configuration directly supports grid stability by reducing the need for distant transmission and provides immediate energy resilience during peak demand or outages.

This trend moves toward more reliable, cheaper electricity for households and communities—critical for food access and disaster recovery. As solar-plus-storage becomes more widespread, it reduces the cost of grid-scale energy while strengthening security against supply disruptions. The U.S. and Australian leadership in this space suggests potential for faster adoption in regions with high solar potential.

What to watch: Whether the scalability of these systems translates to widespread community-level deployment, not just large-scale projects. Current data shows promise but remains theoretical in many regions.
